To aZZ whom it may concarn:

Be it known that I, CHRIsToPHER NV. LEVALLEY, a citizen of the UnitedStates, residing at Milwaukee, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements inShaft-Hangers, of which the following is a specificatlon.

This invention relates to hangers or supports for line-shafting, and hasfor its object to produce an article of this character possessing greatStrength and rigidity and in so doing to employ a minimum of materialand that of a character that may be easily fabricated, such as barsteel.

In the accompanying drawings I have represented my improvements asapplied to a ceiling or overhead shaft-hanger, though it is apparentthat by inverting the parts shown a floor support or bracket will beproduced, so that, therefore, my invention is not limited to the exactarrangementI of parts shown.

In the drawings, Figure 1 is an elevation of a shaft-hanger embodying myimprovements, the shaft being represented in vertical section and thebearing therefor in end view. Fig. 2 is an edge view. Fig. 3 is aninverted plan view of the lower part of the hanger. Fi 4 is anelevation, Fig. 5 an edge view an Fig. 6 an inverted plan view of thelower parts of a hanger of somewhat different construction from thatshown in the other views.

The shaft-hanger that I have illustrated embodies the following membersor parts, viz.: two depending side members, two cross members, andsupports for the shaft-bearing carried by the cross members. The sidemembers aredesignated 2, 2, and are provided with out-turned or feetportions, 3, by which the hanger is attached to its carrier or support.The cross members extend between the sidemembers and are secured theretoso as to form a rigid Structure, the upper cross member being designated4, and the lower one 5. These four parts, when assembled, inclose anopen space in which is situated the line-shaft A, and the bearingtherefor, B. The) screw adjusting devices, C, between which theshaft-bearing is supported are carried by the cross members of thehanger.

To insure a rigid connection or union betweenthe side and the crossmembers and to form a stifi hanger from a minimum of material, theportions of these parts that come together should possess considerableexpanse, that is they should have relatively broad meeting faces. So faras the upper cross member, 4, is concerned this result is easilyattained by bending the ends of the cross member, as at 6, so that theylie parallel with and against the inner faces of the side bars, 2, towhich they are Secured by bolts or rivets.

It is desirable that the lower cross member, 5, should be so attachedthat it may be swung out of the way of the line-shaft, when that is tobe moved into or out of the hanger, without entirely disconnecting itfrom both the side members; and in order to permit this, as well as toretain the broadfaced connection between this part and the side membersI construct these parts as shown in the drawings, that is, the lower orouter end of each side bar, 2, is twisted or bent so as to occupy aplane at right angles to the main art of the bar and transverse to theaxis of the line-shaft, as indicated at 7. The end portions of the crossplate or bar 5 are likewise twisted or bent to occupy planes at rightangles to the middle part in which the screw adjusting device C ismounted, so that these end parts, 8, may lie flat against the bentparts, 7, of the side bars, to which they are Secured by the bolts, 9.By loosening one of these bolts and removing entirely the other thecross bar or plate, 5, may be swung down, as indicated in dotted linesin Figs. l and 4, to open the space in which are situated the shaft andits bear-V ing. lVhere the line-shafting is so heavy as to make itVundesirable that the bolts 9 should carry the entire weight thereof,the extreme end portions of the depending hangers, 2, may be bent, asindicated at 10, Figs. 1, 2 and 3, to constitute lips or Hanges directlybelow the twisted end parts of the cross member, 5, upon which thelatter may rest. VVhen thus Constructed the bolts are relieved of mostof the strain from the weight of the shaft, but it is necessary toloosen the bolt, on which the cross piece turns to open the space intothe `hanger, somewhat more than when the ends of the side bars are notflanged; the latter construction being represented in Figs. 4, 5 and 6,and being preferable under some circumstances.

In constructing a shaft-hanger from bar metal, it is practicallyimperative that the broader faces of the bars that constitute the sidemembers of the hanger should be arranged in planes substantiallyparallel with the axis of the line of shafting, with the result that theside bars, alone and of themselves, do not always impart to the hangerthe necessary strength and Stiffness to resist lateral or transversestrains. I therefore, when circumstances make it desirable, brace andstiffen the side members of the hanger. As represented in Fig. 1, Iarrange a pair of crossed brace pieces, 13, between the side members, 2,these being locatedbetween the foot portions of the hanger and that partin which the shaft is situated. I prefer that the braces, 13, should beformed integrally with the cross member 4, these parts being formed froma single piece of bar metal shaped as follows: its central part is leftflat to constitute the cross member, 4, on each side of the cross memberthe bar is bent to form the parts, 6, that lie against and are Securedto the inner faces of the side members of the hanger, while beyond theparts, 6, the legs of the bar are each given a quarter twist or turn, asindicated at 15, and at the same time bent so that the two parts, 18,that constitute braces, cross each other like the letter X and extendbetween the opposite side bars of the hanger. The ends of the braces,.and of the bar being described, are twisted, as indicated at 16, toconstitute feet or bearings that are adapted to be secured to the sidemembers, 2, near the foot portions, 8, thereof. WVhere the braces, 18,which lie against each other flatwise, cross they are preferably unitedby a bolt or rivet, 14.

I have represented one of the side members of the hanger as beingfurther Strengthened and stifi'ened to resist lateral or transversestrains, for which purpose I form it of a trus's-like construction. Itis evident that both of the side members could be thus Constructed, ifthat were found desirable, but ordinarily the transverse strains on ashaft-hanger are principally in one direction. 11 indicates a bracemember extending from the outer end of the foot portion of the sidemember to the main body part thereof adjacent to the space in which theshaft is located, preferably to just above where the twist to form thepart 7 begins. This brace has its ends bent, as at 11' so as to lie flatagainst the foot, 3, and as at 11 to lie against the outer face of theside bar 2, and is Secured to the side member by bolts or rivets. It isevident that this brace need not be a part entirely distinct from theside member with which it is associated, but that instead it might beintegral therewith, the foot portion being continued to form the brace.

12, 12 indicate vertieally disposed guides between which theshaft-bearing B is arranged, and with which it engages. I prefer thatthese guides should be formed of bar steel and that they should be soshaped as to have the vertically disposed middle portions, and the bentend portions that are united respectively with the upper cross memberand with the side members. The parts 12 operate not only as guides forthe shaft-box or bearing, but also to strengthen and stiffen that partof the hanger in which the shaft is located, while the braces 11 and 18operate to strengthen and stiffen the hanger between the part stiffenedby the guides 12 and the foot portions 3.

By giving to the members, 2, 5 and 13, of the hanger the quarter turnsso as to permit the engaging parts to be brought together flatwise asdescribed, the full strength of the material from which these parts areconstructed is maintained and utilized.

Having described my invention'what I claim and desire to secure byLetters Patent is:

1, A shaft-hanger having side members formed of bar metal, each of whichis, near its outer end, transversely twisted so as to give to theimmediate end portion a one fourth turn to cause it to lie in a planesubstantially transverse to the aX-is of the shaft, and a cross memberSecured to the said turned end portionsV of the side members,substantially as set forth.

2.

(S. A shaft-hanger comprising a pair of side bars, a cross memberextending between the side bars near their outer ends, and another crossmember extending between the side bars intermediate between their ends,the opposite ends of the lastsaid cross member being bent to lie againstthe inner faces of the side bars to which they are connected, andextending thence across the hanger to the side bars to which they areconnected near the attaching end, substantially as set forth.

7. A shaft-hanger having side members, cross members arranged betweenthe side members for supporting the shaft, and arranged to inclose aspace in which are situated the shaft and its bearing, and guides havingvertically disposed parts with which the shaft-bearing is adapted toengage arranged within said inclosed space an secured to the saidmembers of the hanger, substantially as set forth.

8. A shaft hanger comprising side members, and cross members between theside i members, these parts being arranged to inclose a space in whichare situated the shaft and its bearing, in combination with guideshaving vertically disposed parts with which the shaft bearing isarranged to engage, each guide at one end being connected with the uppercross member and at its opposite end connected with a side member.

9. A shaft-hanger the parts of which are formed of bar metal, and comrising the side members 2, the ends of whic 1 are given each a quarterturn to cause their end portions to occupy planes substantiallytransverse to the axis of the shaft, an upper cross member, a lowercross member, 5, the ends of which are each given a quarter turn and.lie fiatwise against the turned end portions of the side members, andthe vertically disposed guides 12, substantially as set forth.

10. A shaft-hanger having side members of bar metal and crossed bracesformed of bar metal and extending between the side bars, portions ofthese braces located between the side bars 1 ing in planes transverse tothose occupie by the side bars, and the braces having their ends bent topresent bearing or attaehing feet secured to the inner faces of the sidebars, substantially as set .forth.

11. A shaft-hanger having side members formed of bai` metal, a crossbar, 4, and braces 13, between the side bars, the cross bar and thebraces being integral, and the metal of which they are formed being bentto form attaching faces that are adapted to lie against the inner facesof the side members and be Secured thereto, and to cause the braces tohave their flat faces in contact where they cross, and to lie in planestransverse to those occupied by the side members, substantially as setforth.

In testimony whereof I affix my Signature in presence of two witnesses.
